TestServerGetInfoAll, TestServerGetInfoSingleAndMissing and
TestServerGetStatusAll indexed the decoded response by uuid at the top level,
but utils.SendSuccessResponse wraps the payload as {success, message?, data:{...}}
— the shape the console reads as response.data[uuid] (frontend/src/api/index.js).
The uuid lookups therefore always missed, and unmarshalling the nil raw message
surfaced as "unexpected end of JSON input".
decodeResponse now decodes the envelope, asserts it is a success carrying a data
object, and returns that object. The handlers are unchanged: they already return
the documented shape.
